You will get a custom two-way API integration between your systems (REST/OAuth2)


Project details
You will get a reliable, two-way integration that keeps your systems in sync — without duplicates, and without silently breaking.
Most integrations fall over on two things: OAuth2 token refresh and de-duplication. I handle both properly, add clear logging so you can see every sync, and build it to keep running.
What you can expect:
• A clean mapping of the objects and fields to sync
• Two-way sync with OAuth2 auth and automatic token refresh
• De-duplication and error handling so data stays clean
• Webhooks/scheduling so updates flow in near real-time
• Logging and a simple status view — no black box
I'm a Sydney-based developer with 10+ years building REST/OAuth2 integrations across .NET, Node.js and Python. Clear communication, honest timelines, and code you own.
Not sure which tier fits? Message me with the two systems you want connected and I'll point you to the right package.

About Lukie
Full-Stack Developer | .NET, React, Node & Azure | SaaS, APIs & AI
Ryde, Australia - 1:57 am local time
What I can help you with:
• SaaS & web apps — multi-tenant platforms with billing, user roles, dashboards and reporting
• Payments & subscriptions — Stripe billing, invoicing, and the full signup-to-renewal lifecycle
• API & system integrations — two-way REST/OAuth2 integrations that stay in sync and don't silently break
• AI & automation — LLM-powered features, agents and automations wired into your existing tools
• Maintenance & support — keeping existing sites secure, fast and online
Recent work includes a multi-tenant gym-management SaaS (.NET + React, Stripe billing, QR check-in, e-signature), a hosting/domains customer portal integrating an external reseller API with Google/Microsoft sign-in, and an AI real-estate visualization platform on Azure.
Tech I work with: C#/.NET, React, Next.js, Node.js, TypeScript, Python, PostgreSQL/SQL Server, Azure & AWS, Docker, and Stripe — backed by real automated testing.
How I work: clear communication in plain English, careful changes to production systems, and a simple record of what changed and why. Every line of code is written to be maintained and extended as your product grows.
Looking to build something new, integrate two systems, add AI, or keep an existing app healthy? Send me a message and let's talk it through.

Discovery & mapping
We confirm the two systems, the objects to sync, the sync rules and the dedupe key.
Build & connect
I build the integration with OAuth2 auth, token refresh and logging, and test it against your systems.
